BENCH -PLANE.

$L-ECII 'I-C-'Ai'ION forming part of Letters Patent No. 339,872, dated April 13, 1886.

' Application filed January 16, 1886. Serial No.198fi70.

To all/ whom it may concern:

Be it known that I, JOHN PoRcrUs GAGE, a citizen of the United States, residing at Vineland, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Bench-Planes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a vertical longitudinal section. Fig. 2 is a perspective view of one of the clampingplates. Fig. 3 is another view of the same plate. Fig. 4 is a perspec tive View of the tool, and shows the clamp upon the upper side or front. Fig. 5 is a rear View of the tool, and shows the clamp upon the rear or under side.

This invention has relation to improvements in bench-planes; and it consists in the construction and novel arrangement of parts, hereinafter set forth, and pointed out in the claims.

The object of the invention is to provide a bench plane in which the bit or cutting-tool may be properly adjusted both laterally and longitudinally, and when adjusted laterally the longitudinal movement will be in a straight line, and with its edge parallel to the lower surface of the plane-stock.

In the accompanying drawings, A designates the plane-stock, of rectangular shape, and provided with the handles a a, firmly secured by screws or otherwise to its upper surface, and respectively near its front and rear ends.

a is the slot for the tool-holder in the planestock.

Bis the holder for the bit or cutting-tool, secured in the slot a". The holder B is provided with the inclined rear plate, I), secured in the slot a by means of the slots b and screws b and the parallel side plates, b If, which lie against the side of the slot a", and are connected by the transverse rod 1), as shown.

(N0 model.)

If desired, the tool holder may be so made as not to extend through the stock.

0 is the bit or cutting-tool, provided with the series of transverse slots 0 c and a proper cutting-edge at its lower end.

0 is a clampingplate, through a central opening in which the screw 0 passes. The said screw also passes through any one of the slots 0 of the tool, upon the front surface of which the clamp rests. The end of the screw 0 engages in one of the threaded openings (1 d in the guide-clamp D, which lies upon the rear surface of the tool 0.

The clamp D consists of a rectangular plate, d, and a gnidc-block, (P, on the rear surface of said plate. The block d has at its upper end the semicircular recess d, open at top. Into this recess the disk b enters and turns freely therein, the block (I passing through the slot 1) of the tool-holder. The sides of the block are squared, and made of proper dimensions to fit snugly within the slot.

It is evident from the foregoing that by turning the screw b up or down the cuttingtool 0 may be raised or lowered, and that the slot b will form a guide for the block d and for the tool clamped thereto by the means described, so that the edge of the tool, being made parallel to the lowersurface of the stock, will always remain so, either when raised or lowered. Should the edge be not parallel to the bottom, the tool can be partially rotated between the clamps C and Dby hand-pressure or by a light blow from a hammer, the screw 0 being loose enough to permit this. The slots 0 allow the position of the clamps O and D on the cutting-tool to be varied when necessary. Each slot 0 also allows the tool to be adjusted laterally between the clamps.

1 opening in the plate E near its upper edge,

and impinging upon the surface of the clamping-plate O. The said screw does not possess sufficient hold on the plate to prevent the adjustment of the cutting tool.

By the construction described the necessity of setting the cutting-edge of the tool parallel with the bottom of the stock every time the said tool is moved or taken out is avoided, as the tool will keep permanently parallel there with if the'adjusting-clanip is not changed nor the cutting-edge Worn unevenly.

Should the plate E be removed, the tool may at any time be taken out of the stock and replaced without altering the adjustment, as all the other parts must hold their relative positions to each other without the adjustingscrew b has its position changed.

Having described this invention, what I a t I 339,872

claim, and desire to secure by Letters Patent,

1. In a bench-plane, the combination/with the plane-stock, the tool-holder, slotted as de scribed, and the adjusting-screw b, moving in a threaded opening in said tool-holder, of the tool 0, the clamping-plateO on the outer side of the tool, and the clamp D on the under side thereof, thesaid clamp being provided with the block d, passing through the slot b of the tool-holder and having the recess d, which engages the disk 6 of the screw b, and the screw holding the clamp to the tool, substam tially as specified. V

2. In a bench-plane, the combination, with the plane stock and tool-holder, constructed as described, of the clamps C and D, the tool 0, arranged between the said clamps and having the transverse slots 0, and the screw 0, for

securing the clamps to the tool, substantially JOHN POROIUS GAGE.
